Judging from the still pic and the video, there are two aspects to the picking/grooming.

Part of his abdomen appears cleanly picked in a manner fairly common to cockatoos. Do you see many feather follicles in that area, or just skin? I suspect he has been working on that section for a very long while.

The video of scattered grooming on the wings and back seems typical behavior. Some areas, particularly on the forward wing-joint appear to be overly groomed to a minor degree.

Overall he looks pretty good with the exception of the abdomen. You may find over time he mellows the behavior a bit, though with cockatoos one never knows.

Sometimes I see feathers follicles. Today was almost the perfect day for him. He was interacting with all of his toys! He was super hyper and I made the mistake of closing the door to his cage and he bite me super hard.

If you automatically think I'll just close his door and then you go straight over to do it, it will be perceived as a sudden movement which will unnerve Peanut. Until he gets very comfy with you around and doing things, knows you won't harm him you almost have to ask permission first. Try engaging him, tell him what you are going to do and then if OK go ahead. When you get to the point that they just carry on doing whatever and you feel ignored then it is OK, you have trust. Remember though even if you think he isn't watching everything going on, he is! They miss very little.

sorry not sure how to post a new post, I'm new to this, But i'm having the same problem with my goffin, I got him last friday so will be a week i've had him, He is adorable, very very gentle. Loves to be held and loves to get on your shoulder. He is bald on one leg, part of his back, and chest. He has also been to the vet and good bill of health. I've put him on pellets and avicalm, He is consitstley doing it when he is on me, he doesn't do it as much in his cage, i know things are not going to change over night, But he wants on my shoulder and wants love every day but he picks more when he is out and on my shoulder. He has all kinds of toys and things to chew. Seem like when he is getting attention he goes crazy and starts picking at his feathers. How can i stop this. please help..

from what I can tell considering peanut's history and how he is seeming to calm the plucking now it feels to me like a habit he learnt from when he was in the cage all that time, which is to say the during those years he was simply bored and began preening as something to do. Over time it's evolved into a behavior he does simple because its what he knows to do. Hopefully over time he will calm down, learn to interest himself with toys and general playing and his feathers will hopefully grow back.

Sounds like you got a potentially very happy friend ready to break through his past for you
